Fig. 6From: Parecoxib reduced ventilation induced lung injury in acute respiratory distress syndromeHistopathological analysis of lung tissue. a, d Sham group. b, e VA group. c, f PVA group. a–c × 200. d–f × 400. Lung tissue in the VA group showed thickened alveolar walls, edema, decreased alveolar space, and obvious inflammatory cell infiltration and hemorrhage. Parecoxib significantly decreased the degree of MV-induced histopathological injury (n = 8 in each group)Back to article page
